I am still in Ch. 1 and have exhausted all possible quests so far except for the 5 golden blade pieces for Oskar. My problem may contain spoilers for that quest:

Click to reveal..

I have 4 pieces from Craig, Brogar, excavation site, and Dorgan. That leaves Luis who still has one. According to a walkthrough, he gives it to you after the dialog option to give him 2 bottles of beer. However, I made the mistake of offering just 1 beer. Now the 2 beer option doesn't show up any more. How do I get the last piece short of killing him? Is he an important character for later in the game?

This is the second time I am restarted the game due to another error and I just don't want to restart again.

I don't get the pickpocket option any more. I may have used it up earlier or it's not available. I guess I will leave the camp for a while to level up some more in order to fight for his gold sword piece. Unfortunately he is no longer alone at his fire and I will have to fight 2 at once. How I wish I hadn't been stingy with that extra beer!

Type 'minsky' during gameplay and press [Enter] to enable the test mode console. Then, press ~ or [F1] to display the console window. (I found that if you go into inventory mode first then you can type in the minsky otherwise you have to type it really fast.

This shows the code but I don't know if it works or not. You can google for a list of item codes for risen if that doesn't work.

Thank you, oldman!! You are a genius! I was able to get the missing piece. I knew I had taken all 5 but only 4 showed in inventory. Your link showed that others had experienced that glitch. Your help saved me from quitting the game.

I'll worry about the Titan when I get to him. I am playing on easy setting and yesterday I came across my first lizard priest and that was challenging enough. I must have died a thousand deaths. Finally I got to a point where I was very close to killing him ... then the doorbell rang ... UGH!! Guess what happened!
